The gain hemispherical radiation pattern, and axial ratio of the Archimedes spiral antenna can be predicted using thin wire moment method which is studied in this paper. The method can predict without backing, with acceptable ...

A technique for the determination of the electric field at arbitrary points in the space surrounding an antenna is described. The cylindrical modal expansion formulation of the electric field can be evaluated using A. C. ...

The Finite-Element Method has emerged as an important tool in computational electromagnetics. Accurate solutions require fine meshes, with commensurately large computational requirements. We discuss the use of adaptive ...

In this paper, we combine and extend two of our previous works to provide a more complete solution for the GPU acceleration of the Method of Moments, using CUDA by NVIDIA. To this end, the formulations of the original 1982 ...

One perspective on electromagnetic compatibility activities in South Africa, to stimulate a debate, is presented including some of the review of past works. An overview of known work is discussed and three suggested ...

ENGLISH ABSTRACT: A computational tool for numerical synthesis via optimization is developed. Only
two port waveguide devices are considered. The Finite Element Method (FEM) is
used for the electromagnetic analysis. ...

ENGLISH ABSTRACT: The parallel FDTD method as used in computational electromagnetics is implemented on a variety of
different high performance computing platforms. These parallel FDTD implementations have
regularly been ...

ENGLISH ABSTRACT: An artificial chiral medium can be made by embedding metal helices (chiral or handed structures)
with random orientation inside au achiral hnst medium. The electromagnetic behaviour
of such artificial ...

An educational program in which the PC has played in important role in stimulating interest and research in electromagnetic field theory and antenna engineering among university students is described. By using the PC to ...

The symmetry operations such as spatial inversion and time reversal are illustrated to understand or simplify problems which arise in engineering electromagnetics. Familiar examples are presented, followed by a new, important ...

The capacitance per unit length of a microstrip transmission line is obtained using a spectral-domain Method-of-Moments (MoM) formulation. The paper emphasizes this problem as a teaching tool to introduce students of ...

One of the most important steps in the development of any numerical code is the validation of the implementation by comparison of the results obtained for a set of test cases to the exact solution. In the context of codes ...

An overview of parallel computing is provided, with reference to numerical analysis and, in particular, to computational electromagnetics. The history of parallelism is reviewed, and the general principles are provided. ...
